Description

[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to a technical field related to a mechanism that enables passage of a branch rail point of an up type traveling vehicle.
[0002]
[Prior art]
In general, an up-type traveling vehicle includes traveling wheels that roll on a traveling rail and pinion wheels that mesh with a rack rail. The rack rail is laid between the traveling rails. Therefore, if the Apt traveling vehicle travels in the traveling form as it is, the pinion wheel collides with the traveling rail at the branch rail point.
[0003]
Conventionally, it is known that a traverser is used as a means for enabling the passage of a branch rail point of an up-type traveling vehicle. The first conventional means lifts the entire apt-type traveling vehicle with a traverser installed near the branch rail point, moves it laterally, and moves it above the branch rail point, thereby turning the abt-type traveling vehicle. It is something to be made.
[0004]
As another conventional means, it is known to cut off a part of the traveling rail at the branch rail point. This conventional second means is to form a passing gap of the pinion wheel in the traveling rail by cutting the traveling rail.
[0005]
[Problems to be solved by the invention]
The conventional first means described above has a problem in that it cannot be used inside a tunnel, which is a limited space, because it requires a space for installing and operating a traverser. Furthermore, the above-described conventional second means has a problem in that there is a risk that the traveling wheel is derailed from the portion where the traveling rail is cut off.
[0006]
The present invention has been made in consideration of such problems, and an object thereof is to provide an up-type traveling vehicle having a mechanism that can safely pass through a branch rail point.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the following means are employed in the Apt type traveling vehicle according to the present invention.
[0008]
According to the first aspect of the present invention, there is provided an up type traveling vehicle including a traveling wheel that rolls on a traveling rail and a pinion wheel that meshes with a rack rail, and the traveling wheel and the pinion wheel are supported non-coaxially. A travel drive source is connected to the pinion wheel fixedly supported by the vehicle body, a drive transmission member is spanned between the pinion wheel and the travel wheel, and an axle for supporting the travel wheel is provided. An elevating mechanism that supports the vehicle body and allows the vehicle body to move up and down is provided between the axle of the traveling wheel and the vehicle body.
[0009]
In this means, when the elevating mechanism is operated, the vehicle body is raised and the pinion wheel is pulled up to a position higher than the traveling rail, but the traveling wheel is left on the traveling rail. Therefore, at the branch rail point, the pinion wheel can pass without colliding with the traveling rail.
[0010]
According to a second aspect of the present invention, there is provided an up-type traveling vehicle including a pair of front-side traveling wheels that roll on a traveling rail, a pair of rear-side traveling wheels, and two pinion wheels that mesh with each other. The pair of traveling wheels on the front side and the one pinion wheel, and the pair of traveling wheels on the rear side and the other pinion wheels are non-coaxially supported and fixedly supported by the vehicle body. It is connected a separate drive source is respectively to the first pinion wheel and the other pinion wheel being provided between the pair of running wheels of the pinion wheel and the front of the one, and the other pinion wheel and the rear-side each drive transmission member between the pair of running wheels is passed over the support the axle for supporting the pair of running wheels on the vehicle body, the lifting mechanism that permits lowering the vehicle body, Freon Between the axle and the vehicle body of the pair of running wheels of the side, and is characterized by being separably mounted between the axle and the vehicle body for supporting the pair of running wheels of the rear side.
[0011]
In the above means, the traveling drive source connected separately to each pinion wheel via a drive transmission member spanned between each pinion wheel and each pair of traveling wheels on the front side and rear side. Since the driving force is transmitted, the vehicle body can be moved forward or backward only by rolling traveling on the traveling rail of the traveling wheel.
Further, since two travel drive sources are provided, each can be dedicated to forward or reverse, or both forward and reverse can be switched to use both forward and reverse.
[0012]
In the invention described in claim 3, the rack rail described in claim 1 or 2 is formed by arranging pins in parallel with each other between the opposed groove-shaped steels at a predetermined interval, and the levitating that travels the groove-shaped steel The prevention guide wheel is supported by the vehicle body.
[0013]
Since the levitation prevention guide wheel is supported by the vehicle body, the levitation of the vehicle body can be prevented.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of an up type traveling vehicle according to the present invention will be described below with reference to the drawings.
[0015]
In this embodiment, a battery electric drive type used in a tunnel is shown.
[0016]
The traveling rail 1 and the rack rail 2 on which this embodiment travels are laid on a common sleeper 3 made of H-shaped steel installed on the bottom surface of the mine shaft. The traveling rail 1 consists of two general rails. The rack rail 2 is laid between the traveling rails 1, and in order to prevent accumulation of earth and sand and retention of water and oil, pins 2b are arranged in parallel with each other at a predetermined interval between the opposed grooved steels 2a. What is allowed to be used is adopted.
[0017]
In this embodiment, the vehicle body 5 is formed in a box shape. A driver's seat 6 is provided on the front side of the vehicle body 5. A battery 7 is mounted at the center of the vehicle body 5. Inside the vehicle body 5, two pairs of motors 8 and speed reducers 9, which are travel drive sources electrically connected to the battery 7, are suspended and supported on the side walls of the vehicle body 5 (points A and B) and reversed in the lateral direction. It is housed in parallel in the direction.
[0018]
Two pairs of relatively small-diameter front and rear traveling wheels 10 that roll on the traveling rail 1, and two relatively slightly large-diameter pinion wheels 11 that mesh with the rack rail, Is supported non-coaxially.
[0019]
The axle 12 on which the traveling wheel 10 is supported is supported by the vehicle body 5 so as to be movable up and down. An elevating mechanism 13 composed of a hydraulic cylinder is provided between the upper portion of the axle housing 12 a of the axle 12 and the roof wall of the vehicle body 5.
[0020]
The axle 14 on which the pinion wheel 11 is supported is fixedly supported by the speed reducer 9. The axle housing 14a of the axle 14 is fixed to the housing of the speed reducer 9. The axle shaft 14 b of the axle 14 is connected to the power take-out portion of the speed reducer 9.
[0021]
A relatively small diameter sprocket gear 15 is coaxially fixed to the axle shaft 12 b of the axle 12 of the traveling wheel 10. A relatively slightly larger sprocket gear 16 is coaxially fixed to the axle shaft 14 b of the axle 14 of the pinion wheel 11. A drive transmission member 17 formed of a chain belt is suspended between the sprocket gears 15 and 16. The drive transmission member 17 is provided with a tensioner 18 that applies tension. In addition, a sensor 19 that detects the disconnection of the drive transmission member 17 is provided in the vicinity of the drive transmission member 17.
[0022]
Furthermore, in this embodiment, the vehicle body 5 supports the levitation prevention guide wheel 20 that travels on the grooved steel 2 a of the rack rail 2.
[0023]
In this embodiment, the lower end point La of the pinion wheel 11 at the normal time is located below the upper end point Lb of the traveling rail 1 as shown in FIG.
[0024]
In the embodiment configured as described above, the driving force of the motor 8 that is a traveling drive source is transmitted to the pinion wheel 11 via the speed reducer 9 using the battery 7 as a drive energy source, and at the same time, the drive transmission member 17 and the like. Is also transmitted to the traveling wheel 10 via. Accordingly, when the motor 8 is driven, the traveling wheel 10 rolls on the traveling rail 1, the pinion wheel 11 meshes with the rack rail 2, and the vehicle body 5 moves forward or backward.
[0025]
It should be noted that the two drive systems provided as described above can be dedicated to forward or reverse, respectively, or both forward and reverse rotation can be switched for both forward and reverse.
[0026]
When the branch rail point is reached during traveling, the lifting mechanism 13 is operated.
[0027]
When hydraulic pressure is input to the elevating mechanism 13, the vehicle body 5 is pushed up and raised, and the traveling wheel 10 is pushed down by the reaction force and left on the traveling rail 1. The raised vehicle body 5 integrally raises the pinion wheel 11 that is fixedly supported. The rising width of the pinion wheel 11 is set so that the lower end point La ′ of the pinion wheel 11 is located above the upper end point Lb of the traveling rail 1 as shown in FIG. 3. In addition, since the rising width of the pinion wheel 11 is extremely small, troubles such as contact with other parts do not occur even inside the tunnel. Further, since the rack rail 2 is removed at the branch rail point, the rising prevention guide wheel 20 is not caught by the grooved steel 2a of the rack rail 2 and the vehicle body 5 is not prevented from rising.
[0028]
In the state where the vehicle body 5 is raised, the distance between the traveling wheels 10 and the pinion wheels 11 is extended. Will be absorbed and the transmission of the drive transmission system will be maintained.
[0029]
Accordingly, when the motor 8 is driven as it is, the vehicle body 5 moves forward or backward only by rolling traveling on the traveling rail 1 of the traveling wheel 10. As a result, the pinion wheel 11 can pass through the branch rail point without colliding with the traveling rail 1. In addition, since there is no removal part like the prior art in the traveling rail 1, there is no fear of derailment and it can pass safely.
[0030]
After passing through the branch rail point, when the hydraulic pressure of the lifting mechanism 13 is discharged, the vehicle body 5 is lowered to return to the normal traveling state.
[0031]
A sensor 19 detects when the drive transmission member 17 is fatigue-cut due to frequent fluctuations in the tension of the drive transmission member 17 due to the repeated raising and lowering of the vehicle body 5 described above. Therefore, since the repair can be performed immediately by the detection signal of the sensor 19, the vehicle body 5 is raised at the branch rail point without knowing the disconnection, and the pinion wheel 11 is idled so that the vehicle cannot run.
[0032]
As described above, in addition to the illustrated embodiment, the drive system such as the motor 8 can be constituted by an internal combustion engine or the like.
[0033]
Furthermore, the elevating mechanism 13 can be composed of other devices such as an air cylinder.
[0034]
【The invention's effect】
As described above, the Apt traveling vehicle according to the present invention includes a lifting mechanism that lifts and lowers the vehicle body and the pinion wheels, and can avoid a collision of the pinion wheels and the traveling rail with a slight rise, so that the limited space is limited. There is an effect that can be used for passing the branch rail point even in a mine shaft or the like.
[0035]
Furthermore, since no removal part is required for the traveling rail, there is no risk of derailment, and there is an effect that the branch rail point can be safely passed.
